        abstract = {The  biology  and  morphometrics  of  pulse  beetle, Callosobruchus  chinensis
were  studied on chickpea cultivar  ICCV 2 under  laboratory  conditions at ICRISAT, Patancheru, Telangana, India 
during  2018-19  and  2019-2020.  The  experiments  were  carried  out  in  the 
BOD  incubator  at temperature of 28 {$\pm$} 2?C and relative humidity of 65 to 70\%. The life cyc
le of C. chinensis 
included four stages
egg, grub, pupae and adult. The data revealed that eggs 
incubation period 
in 4-5 days, the grub  stage consisted  of four instars and  its development ranged from 20
-25 days, pupation lasted  for  6-
7  days,  whereas,  female  adult longevity  ranged  from  9
-12  days.  The  morphometric 
measurements revealed that the average length and breadth of eggs were 
0.62 {$\pm$} 0.03mm and 0.34 
{$\pm$} 0.02 mm respectively.  The length and breadth (mm) of four grub  instars G1, G2, G3 and G4  
were 0.58 {$\pm$} 
0.02 and 0.30 {$\pm$} 0.01, 1.53 {$\pm$} 0.06 and 0.92 {$\pm$} 0.04, 2.71 {$\pm$} 0.10 and 1.47 {$\pm$} 0.06, 3.59 {$\pm$} 
0.14 and 1.96 {$\pm$} 0.08 respectively. The average length and breadth of pupa were 3.72 {$\pm$} 0.12 mm,
2.15 {$\pm$} 0.09 mm. Whereas, the length and breadth (mm) of  
adult male and female bruchids were 
3.87  {$\pm$}  0.08, 2.07  {$\pm$}  0.05  and  4.23  {$\pm$}  0.14
, 2.31  {$\pm$}  0.07
respectively.  The  total  life  cycle  of 
C.chinensis
ranged from 33
